Local textbooks from South Bend public schools are filled with errors as well, such as that the Founders were secularists, actually 53 of them were leaders in their church, and a favorite of mine is the book my daughter brought home that said that the S&KL crisis that happened in the 1970’s was Ronald Reagan’s fault (he wasn’t elected until 1980). I also run an experiment; whenever a customer hands me a $50 dollar bill I ask him what war Grant served as a General in. So far not one person with the $50 even knew he served as a General Officer (although one old man in earshot did know).
